Engine-cooling radiator



Dec. 16, 1930. c. OPPE ENGINE COOLING RADIATOR Filed July 21, 1926 Patented Dec. 16, 1930 UNITED STATES PATENT OFFICE f CHARLES OPPE, OF NEW HAVEN, CONNECTICUT, ASSIGNOR TO G & O MANU- FACTURING COMPANY, OF NEW HAVEN", CONNECTICUT ENGiNE-COOLING RADIATOR "Application filed. Jul 21,

radiator, and to the means for attaching the overflow or vent tube to the upper'tank so that it will be held securely in proper position to perform its function.

A radiator used for cooling internal com- 1g bustion engines ordinarily consists of upper and lower fluid tanks connected by a series of tubes or water channelswhich form the cooling section of the radiator. All overflow or vent tube is ordinarily secured in the upper tank, the open upper end of this tube usually being disposed within the filler neck so that, while this tube permits the radiator to be filled to its capacity, it will, when the fluid expands upon being heated permit the excess fluid to drain off so that it will not overflow about the radiator cap. The lower end of the overflow tube is usually passed through thewall of the radiator tank so that the excess fluid isvented upon the ground. One object of this invention is to provide a novel means of securing the filler neck to the upper tank of the radiator.

Another object of the invention is to provide a radiator with a vent tube or overflow pipe secured thereto in such amanner that the same will not become detached or broken,

in service. i

A further object of the invention is to provide a novel andeconomical method of securing the vent tube or overflow pipe to the radiator filler neck.

Still another object of the invention is to provide an improved means for securing the overflow or vent tube in place against the wall of the filler neck of the upper tank of the radiator so firmly that it will not bedisplaced in use, and at the same time provide a connection of this character which maybe economically and cheaply made. e

To these and other ends the invention consists of the novel. features and combination of parts to be hereinafter described and claimed.

In the accompanying drawings:

1926. Serial No. 124,052.

Fig. 4: is an enlarged sectional view through the upper filler neck of the radiator taken on line H of Fig. 5 and showing a modified form, of my invention;

Fig. 5 is a sectional view on line 5+5 of Fig. 4.

The radiatorwhich I have selected to illustrate as embodying my improvements comprisesv an' upper tank 10, a lowertank 11, between which is the usual cooling section 12. Upon the upper tank 10, andcommunicating with the interior thereof, is a filler tube 13 which is threaded at 14 to receive the usual cap 15. p 7

Referring to Fig. 2, it will be seen that the radiator tanklO is provided in its upper surface with an openingsurrounded bya flange 16, the flange being turned upwardly from the metal of the tank so that it assumes a substantially vertical position. The lower end of the neck or tube 13 is inserted within this flange, and-is of such a size as to fit fairly snugly therein so that a soldered connection maybe made between these two parts to effect a water-tight joint; that is, after the lower end of the filler tube has been inserted within the flange 16 the space between the, neck and the flange maybe effectually filled with solder so that all danger of leakage is obviated. v i a As shown in Fig. 1,v an overflow or vent tube 17 is disposed within the upper tank of the radiator, the upper end 18 of this tube extending to apoint within the filler neck andadjacent the top thereof. The lower end 19 of this tube extends without the radiator so 1 that it may discharge the excess fluid upon such a manner that the tube 17 may be inserted between this loop and the side wall of the neck. It will be noted that the loop 20 is of relatively narrow width, and that the overlap between the lower end of the filler neck 13 and the flange 16 is of sufficient width so that when this loop is struck out from the neck sufficient material 22 will remain to make a tight joint with the flange 16 adjacent the loop.

lVith this construction I am enabled to use aportion of the metal of the filler neck itself to hold the vent tube in positiom'and at the same time make a tight connection between the neck and the upper tank of the radiator so that. there is no danger of leakage.

The tube 17 fits snugly between the loop 20 and the side wall of the filler neck so that it will be heldsecurely in position and will not be displaced by the shocks to which it may be subjected in use. In practice the tube will usually be secured by solder to the loop 20.

In Figs. 4: and 5 of the drawings I have shown a somewhat modified form wherein the upper tank 10 of the radiator is provided gto this wall, the width of the tongue 23 being of such a dimension that it may be provided with an opening 24 through which the tube 17 may be inserted. It will be noted that the junction 25 of the tongue 23 with the Wall of the filler neck is disposed at a substantial distance below the upper edge 26 of the flange 16, so as to permit asuflicient overlap of this flange and the side wall of the filler tube to make a tight joint when the solder-is applied between these two parts. I

I am enabled in this construction also to use a part of the metal of the fillerneck to embrace the vent tube and' secure it in place, and at the same time leave sufiicient overlap'between the filler tube and the flange upon the upper radiator tank to make a water-tight joint in the manner described. It will also be apparent that the vent tube'will be held firmly in place and will be held closely against the wall of the filler neck so that it willnot ordinarily interfere with the filling of the radiator; that is, when the radiator is being filled no appreciable part of the water will enter this tube.

While I have shown and described some preferred embodiments of my invention, it is to be understood that it is not to be limited to all the details shown but is capable of modification and variation within the spirit of the invention and within the scope of the appended claims.

That I claim is:

l. A radiator for internal combustion engines having a tank provided with an opening in its upper side, a filler. neck connected with said opening and extending upwardly ing upwardly from said opening, a vent tube having its end extending from the tank within said filler neck and a part of the metalof the filler neck being displaced inwardly to engage the remote side of the vent tube and secure it in place;

8. A radiator fol-internal combustion engines having a tank provided with an opening in the upper side thereof, and a filler necke'xtending upwardly from said opening, a vent tube having its upper end extending within the filler neck adjacent the wall thereof, the metal of said filler neck at the lower end thereof being displaced inwardly to provide means to embrace the vent tube and hold it in place.

4:. A radiator for internal combustion engines having a tank provided with an opening in the upper side thereof, and a filler neck secured to the tank within said opening, a vent tube having its upper end extended within the filler neck and adjacent the wall thereof, the metal of said filler neck at the lower end thereof being displaced inwardly to provide means to embrace the vent'tube and hold it in place.

H j g 6.
